We are facing a situation where we are packaging an eclipse rcp.
To support, muti-user usage, we have allowed user-specific workspace creation, using:
osgi.instance.area.default=@user.home/app_name/version_num
version number (specified in the .product file in the main plugin) is being used to distinguish between older workspaces...
The goal is to delete the older workspaces during a new launch of a just installed product.
For that I seem to be needing two things:
-product version number (that currently sits in the aboutText branding property)
-doing this deletion only once (the first launch of a new installation)
So, my question is:
1. From the IProductConstants I am not able to find a property called "aboutVersion"
just like "aboutText", so how do I then get the version_num at runtime? This will help me create a path to the older workspace which I can then delete...
2. How do I detect the first launch of a newly installed product...is there support in the API already?
If not, my current idea is to have a preference (Defaulted) and then change it ...that sort of simulates the first launch detection....
3. Am I on the right track, is this a recommended way of dealing with the above problem?

Thanks for your prompt reply Brian.
So, before posting here, I did try (what Brian has suggested). On application launch, I am able to retrieve the version number (using some textual parsing of aboutText property) using the getBrandingProperty() method defined in IApplicationContext.
My followup questions related to this are:
1. The version number that gets transferred to "aboutText" property in plugin.xml when I hit synchronize on the App.product "overview" gui, is that available as a separate property by default?
As of now, the only properties that are default available seem to be:
ABOUT_IMAGE, ABOUT_TEXT,APP_NAME and others but no version number...
2. So, I tried a workaround for this defining my own property (in the runtime.products extension) in plugin.xml called "VersionNumber"
This works fine since I am able to retrieve this in getBrandingProperty("VersionNumber") during application launch...but I am having to enter the version number manually in plugin.xml
But, I am wondering if I can specify (linkage) for "Version" in App.product and the corressponding "VersionNumber" property (that I have defined) in plugin.xml
3. Basically, I would like to change the version number in the App.product "overview" gui, then hit "synchronize", this should ideally transfer the
version number to both following positions in plugin.xml:
1. aboutText property (this is happening by default)
2. "VersionNumber" property (not happening)
Without this linkage, I would then need to change the version number in two locations
before exporting product...(would like to avoid that)
4. Also, as an aside, I noticed that the .eclipseproduct (after exporting the product) that is created contains the version of the launcher plugin. Is that by design, I would think it should contain the version number specified in App.product, no?
